# Explain a little background at install time.
print q(
    This module installs a wrapper script 'cleartool.plx'.  Typically
    you'll want to access it by a shorthand such as 'ct', 'cl', 'clt',
    'Ct', or even just 'c'. This must be set up by hand and may be
    done on UNIX via a symbolic link, e.g.:

	% cd /opt/local/bin; ln -s cleartool.plx ct

    or on Windows by making a tiny ct.bat file containing:

	@echo off
	perl //UNC/path/to/cleartool.plx %*

*NOTE*  There are additional 'overlay' modules available which
*NOTE*  extend the functionality of this module.
*NOTE*  Consider ClearCase::Wrapper::DSB, ClearCase::Wrapper::MGi, etc.
